VACUUM-CLEANER.

Be it known that 1, Joan W. France, a citizen of the United States,=residing at Annandele in the countyof Hunterdon, State of New Jersey,have invented certain new and Mseiufl Improvements in Vacuum-Oleaners;and l doherehy declarethe following to boafull clear, and exact descritionof the invention, -tsuch aswill enable 0t ers skilled in the art towhich it appertains to make and use the same.

This invention relates to new and useful improvements in vacuumcleaners.

An object of this invention is the provision of an apparatus which issoconnected to a vacuum gro'ducingdevicethat when the same is peace over asurface,.the dust and other accumulations will be swept into theapparatus from whence it will be conveyed to a convenient receptacle. 1

A furtherobject of this invention is to improve and simplify vacuumcleaning devices rendering them comp'arativel simple and inexpensive tomanufacture, re iable and efficient in use and readily operated.

With the above and other objects in view this invention resides in thenovel features of construction, formations, combinations andarrangements of parts tobeshereinafter more particularly described,Qclaimed and illustrated inthe accompanying drafwingsgm which: a gFhgurel is a side 618Vl3l011q0f ink proved vacuum cleaner. :Fig: 2'-is;atop ,xplan view thereof.

while .the .opposite ends 16 of the said casing ex end in parallelrelation to each other adjacent the upper end of the said casing atwhich point they are curved inwardly as at 17 to meet the lower end ofthe said tubular extension 1,3.

The lower terminals of the ends 16 of the casing are offset as indicatedby the numeral 18 .and have formed integrally thereon spaced plates 19which extend in parallel relation to the-end walls 16, to theintermediate portion of which :they are connected by sleeves 1-8 formedintegrally upon the said plates 19and end walls 16. The lower terminalsof the plates 19 extend slightly below the ofiset terminals 18 of theWalls 16, as lndicated by the numeral 19 to produce shoulders 20 for theengagement with slidmg shoes 21 which are removably secured to the lowerends of the said. casing by counter- PatentedN0v.4,1913.

sunk screws or bolts 22 threaded through the I ofi'set extensions 18..These shoes 21 are used to slide over carpets or the like, but when itis desired to clean hardwood floors these shoes may be removed andreplaced by felt lined supporting shoes 23 as indicated in ,Fig. 7 Theplates 19 have extending through their central apertures 24 studs 25which support keyed to their outer ends pinions 26. The oppositeends-of-these studs 25 are enlarged as at 27 for engagement-with thesleeves 18, the said enlargements being provided with confrontingsockets-28 forengageme'nt with the outer terminalsof a pair oishafts 29.These shafts 29 extend through score 30 for engagement with the angularopenings formed in the enlargedlpoctions of the studs 25 and serve tohold the studs against displacement and also to cause the shaits torotate upon the rotation-of said studs. ,:The core30 is provided-with aeen- I t'ral passage or socket 31 into which extend the adjacent ends of.the shafts '29; These shafts are provided with o rating fingers 32constituting a means an ereby the said shafts mayl-hemovedinwardlyagainstthe tension of a spring 33 whichsurrounds the adjacent enldsoflthe shafts and normally forces them-into engagement with theostuds.

ertically tmovahle' .plates 34 are slidable upon-the studs 25 andareprovided with stud receiving slots 35 tor the reception of the sametopermit of vertical move ment. These plates 34 are circular in forma- 7tion and provided with concentrically disposed outwardly extending pins36 which engage inwardly directed sleeves 37 formed y upon the innerface of the supporting wheels 38. These supporting wheels 38 areprovided with inwardly extending annular flanges 39, the said flangesbeing internally.

toothed,'as indicated b the numeral 40 for.

engagement with a pinion 4l-mounted upon a stub shaft 42 carried by. thelate 19. This pinion 41 meshes with the be ore mentioned pinion 26thereby imparting a rotary movement to the core upon movement of the wmachine which causes the rotation of the wheels.

- The'flanges 39 are peripherally grooved as" at 43 for engagement withrubber tires 44,

' thus serving to absorb noise caused by the w passing of the machineover rough or uneven places. The core 30 is provided with a plurality ofradially extending bristles 44 which are of sufiicient length to engagethe surface of the floor upon which the machine operates and therebyuponits rotation agitate the dust and dirt which is then removed through thetube 15.

In order to normally hold the wheels in their relative position withrespect to the brush 45 formed by the core and bristles extendingtherefrom, the plates 34 are each provided with inwardly extending ears46, each of which is provided with a threaded aperture 47 for receivinga screw 48. This screw 48 is provided at its outer end with 'tionthereto. The-opposlte en walls 16 of the casing-11 are connected barcuate plates 55. These. plates are spaced om each other at theirupperends to produce passages 56 which communicate wlth the o ening 57 formedat the juncture of the casing 11 and tubular extenslon 13. Thelowerterminals of the said plates are slotted to produce passages 58through which and through the assages 56 the dirt or the like will besucked y 'thelvacuum producingbapparatus connected with the tubular memer .15.

The dust or other similar light substance will be drawn through the tube15 into a is itable yac'uum producing apparatus not shown inthedrawings, while a1 heavy substance such as sand or the like will beswept 05 through the openings 58 and permitted to thumb wings 49, whilethe inner terminal is rest within the bottoms of the passages 59locatedbetween the side walls 12 of the casing 11 and arcuate plates 55.The heavy matter may be removed therefrom upon the removal of the shoes22 or 23. 0 From the foregoing disclosures taken in connection with theaccompanying draw- .ings, it will be manifest that a vacuum ,cleaningapparatus is provided which will fulfil all the necessary requirementsof such a device.

' 'Havin thus fully described this invention what I c aim as new anddesire to protect by Letters Patent, is:
